Maven package finder possible improvements

Proposal

• Is this really necessary? https://gitlab.com/gitlab-org/gitlab/-/blob/bd1042a39ad182abcb5cc7d3b73ad60eaeea3fc7/app/models/packages/package.rb#L139
  • This will load the project relationship
• Can we transform https://gitlab.com/gitlab-org/gitlab/-/blob/bd1042a39ad182abcb5cc7d3b73ad60eaeea3fc7/app/finders/packages/maven/package_finder.rb#L43 with matching_packages.with_version(nil).exists?
• Implement #287638 (closed)
